Stevenson Screen

        Hello again, this is going to be my second official post and the first post about the topic that this blog is going to be about. that is Technology that is used in geography.

Stephenson screen

        The Stephenson screen is like a box that contains meteorological equipment and protects them from direct heat and radiation from outside, it does have slits on the sides so air can pass through and around it inside.

        The Stephenson screen isn't a piece of geographical equipment itself however it does contain meteorological equipment such as a thermometer, a hygrometer, a dewcell, a barometer and a thermograph. The purpose of the Stephenson screen is to provide a dry environment in which you can measure things such as the temperature, humidity, dewpoint and atmospheric pressure.
